Malleability. Malleability is often categorized by the ability of material to be formed in the form of a thin sheet by hammering or rolling. This mechanical property is an aspect of plasticity of material. Malleability of material is temperature dependent. With rise in temperature, the malleability of material increases.

The conclusions are reached through experimental work, wherein the material properties of the two steels are compared. The difference in ductility is related to the difference in Barkhausen Noise Amplitude (BNA) through the grinding process such that the increased ductility is believed to increase the chip build up in the grinding wheel, thus ...

Abstract. A thermal model for the grinding of quenched alloy roll steels has been developed. The temperatures in the cutting area are calculated by this model, and the effect of grinding conditions on the structure and hardness of the surface layers of a roll steel quenched for martensite is studied.
