Dissipative heat and exchange dispersion on metastability of Gd5Si4

►The response of the magnetic and crystal structure of Gd5Si4 to both isothermal and thermo-mechanical processes is investigated. ►The discharge heat by annealing process is caused by the reduction of lattice constant as well as magnetization behavior. ►No crystal phase change was observed at room temperature. ►The crystallographic slip is investigated by dissipative heat to provide the strength and nature of the exchange.
