Shape memory alloys (SMA): Principles and applications

Shape memory alloys (SMAs) belong to a class of shape memory materials (SMMs), which have the ability to remember their previous form when subjected to certain stimulus such as thermomechanical or magnetic variations. SMAs have received significant attention and interest in recent years in a broad range of commercial applications, due to their unique and superior properties.

This talk will give a general view of these materials and serve as an introduction of the field from the fundamental point of view to the applications.

Study of mechanical milling method in iron-cobalt particles preparation

Mechanical milling is a top down technique to synthesize micro and nanoparticles. High-energy ball mill is a typical mill used in this process. The final morphology, size and microstructure of particles depends on several parameter such as material of grinding ball and container, milling medium, milling time, grinding speed, temperature and milling atmosphere, ball to powder weight ratio, etc.

In this work, ball milling is employed as alternative to chemical methods because of the possibility to get more quantity of particles. The effect of different milling parameters in the microstructure and magnetic properties of iron cobalt particles are studied.
