EFFECT OF HEAT TREATMENT ON THE MECHANICAL AND STRUCTURAL PROPERTIES OF X155CrVMo12-1 STEEL
This paper investigates the effects of oil quenching and tempering at various temperatures on the mechanical and structural properties of X155CrVMo12-1 tool steel. The steel specimens were austenitized at 1030 °C for half an hour, followed by quenching and tempering at different temperatures. Mechanical properties were assessed by measuring the...

THERMAL AND MICROSTRUCTURAL ANALYSIS OF THE LOWMELTING Bi–In–Sn TERNARY ALLOYS
Low-melting alloys, based on bismuth, indium, and tin, have found commercial use in soldering,safety devices, coatings, and bonding applications, due to their low melting point temperature ofeutectic compositions and small differences between their liquidus and solidus temperatures.Based on this, the accurate knowledge of their thermal properties s...

EFFECT OF MICROSTRUCTURAL CHANGES ON PROPERTIES OF COLD DEFORMED SINTERED COPPER AND Cu-Au ALLOY DURING THE ISOCHRONAL ANNEALING
This paper studies the effect of annealing on the microstructure and hardness, microhardness and electrical conductivity changes of cold deformed (ε=40%) sintered pure copper and Cu-4at.% Au alloy. The samples of pure copper and Cu-4at.%Au alloy were obtained by sintering, followed by prefinal rolling, quenching and final rolling with 40% r...
