Effect of aging and step-quenched heat treatment on the martensitic transformation of cuznal shape memory alloy

Abstract EN

There are many parameters affecting on the martensitic transformation of nonferrous alloys such as point defects, pores and heat treatment.

In this work, the effect of aging after direct quenching treatment and step-quenched treatment on the Martensitic transformation of porous CuZnAL alloy are studied.

X-ray diffraction analysis is based to identify phases presence in the microstructure of examined specimens.

Optical microscopy and scanning electron microscopy examinations have also studied for prepared samples.

It has been shown that aging and step-queched heat treatment lead to precipitate some intermetallic compounds in the Martensite matrix which make the lower percentage of shape memory effects for prepared alloy.
