Topic: Iron -- Heat treatment.
Connecting rods are highly stressed members in engines; connecting rods are also called as CON rods are subjected to alternative tensile and compressive loads with inertia loads. Inertia plays a major role in high speed engines due to the fact that the higher inertia and it is neither easy to start and stop the engines. Hence the weight of connecting rod plays a major role in the high-speed engines, here an attempt is made to reduce the weight of the connecting rod by using B 4 C reinforced...

More often than not, welded joints experience failure such as fracture which jeopardize their reliability and ergonomics when put in perspective. Attempting a significant improvement in the mechanical properties of welded joint through heat treatment could ensure joints stability and reduce the costs associated with constant repairs and replacements. In this study, the effects of heat treatments (austempering and normalization) on the mechanical properties of weldments were examined. The...

En 31 steel is widely used for applications like ball bearings and grinding media balls. The sliding wear properties of En 31 steel has been studied in the past, however the data on abrasive wear properties of En 31 steel is limited. En 31 steel was quenched and tempered at different tempering temperatures. Metallographic and hardness studies were carried out on heat treated samples. The hardened and tempered samples were tested using two body abrasive wear testing apparatus. The abrasive...

A composite material can be defined as a combination of two or more constituent materials (individual materials) with different physical or chemical properties, and which remain separate and distinct on a microscopic or macroscopic level within the finished structure. In other words, the constituents do not dissolve or merge into each other, although they act together to form a single material. In this project Al-2024 Metal Matrix Composites (MMC) will be produced using stir casting method by...

This Paper investigated effects of annealing and age hardening on the ultimate tensile strength (UTS) and electrical conductivity of aluminium-nickel cast using sand mould. Pure aluminium melt was alloyed with nickel, which was added in 2% to 10% step 2. Annealing and age hardenings were carried out and obtained results showed that Al-2%Ni alloy has the highest UTS of 604.44MPa. On the other hand, Al-6%Ni Annealed alloy has the highest electrical conductivity, with a value of 6.15 × 107 S/m....

AA7075 is a combination with zinc as an essential alloying component. When contrasted with numerous different steels its quality is very similar. It has greater fatigue strength, however less protection from corrosion than numerous other Al alloy. This paper investigates the possibility of growing elite composites with low cast, for different applications like aviation and automobile. The impact of different reinforcements on the AA7075 based composite has been investigated. The mechanical...

The objective of the work was to investigate effect of an accelerated aging on properties of Al6061/albite metal matrix composites(MMCs) such as age hardening, electric resistivity and micro-structural behavior. The samples were aging at 32, 80, 180, and 320°C for 0.01 to 100 hours. The peak of the hardness and the resistivity values of the MMCs increase with increasing reinforcements and ageing temperatures due to ageing precipitation significantly accelerated because of addition of...

The heat treatment steps were heating at a certain temperature for three hours followed by different cooling methods. Three heat treatments were chosen out of several trials: (i) at 595°C, (ii) at 870°C and (iii) at 985°C. Optic microscope and scanning electron microscope (SEM) were employed for observing the...

Effect of heat treatment on microstructure and mechanical properties of TC21 titanium alloy was investigated. TC21 in annealed condition with an equiaxed α+β structure was solution treated at temperature below β-transus (920⁰C, 15 min) and temperature above β-transus (1020⁰C, 15min, WQ). Aging was applied for both groups of samples (600⁰C, 4h, AC).Treated samples below β-transus showed an equiaxed α+β structure. Samples treated above β-transus have been changed to a solely...

The steel has a wide range of applications in the industry, being of extreme importance in any manufacturing process. The SAE 4320 steel is used in a lot of ways, some of them are the transmission systems like gears and pinions. The heat treatments are used to improve some properties of the steel-like, hardness, ductility, and impact resistance. There are many different types of heat treatment. In this article, it was made the tempering process in water and oil, and the quenched process was...

The excellent property combination of ADI has opened new horizons for cast iron to replace steel castings and forgings in many engineering applications with considerable cost benefits. Thanks to the extensive research efforts made over the past few years, new processing techniques have opened even more opportunities for this very prospective material to acquire better combinations of strength, ductility, toughness, wear resistance as well as machinability. This review analyses the key features...

Titanium and Titanium alloys are utilized in many aerospace applications due to a combination of properties such as high strength at elevated temperatures and relatively low density. However, these materials are problematic to machine and are therefore referred to as difficult-to-cut materials. Compared to most materials, the chip–tool interface temperatures during machining are extremely high, even at lower cutting speeds, and tend to concentrate close to the cutting edge. These alloys when...

The strength of a material is a very crucial design parameter from an engineer’s standpoint for designing a mechanical system with a primary design objective of optimization or minimization of system weight. This is particularly true for designing a transmission system for an automobile as a reduction in weight of the vehicle has a direct and significant impact on fuel consumption and the overall dynamic performance in terms of acceleration and maneuverability. Selection of a gear material is...
