Study of Heat Treatment Technology on Medium-Carbon-Low-Alloy-Steel Large Hammer Formation of Gradient Performance

Abstract:

In view of the requirements of the heat treatment on low alloy steel large hammer head formation of gradient performance, mainly study the effect of austenitizing temperature on the alloy mechanical properties and organizational . The results show that: austenitizing temperatures have little effection on the experimental alloys hardness but have great effection on toughness. At the austenitizing temperature 820°C, the experimental alloy obtained the high hardness and low toughness by quenching, and obtained high toughness and low hardness by normalizing; The quenched microstructure of the experimental alloy is mainly lath martensite; the microstructure after normalizing is pearlite + a small amount of ferrite.
