Abstract
Glass transition and crystallization phenomena of LaAlNi amorphous alloy under rapid heating were studied in this paper. A cylindrical specimen of 2 mm in diameter was heated by induction heating at a rate of up to 1000 K/s. During heating, glass transition temperature Tg and crystallization temperature Tx increase with increasing heating rate. Furthermore, the temperature range of the supercooled liquid state, ΔTx, becomes wider. In addition, deformation behavior during heating was studied under compressive loads. The material exhibits a Newtonian viscous flow in ΔTx, and the normal viscosity of the flow decreases with increasing heating rate.
