ABSTRACT

Plasticity at 250°C changes with increasing Sm content in T5 and T6 conditions differently.

For T5 condition it follows the elongation curve with a minimum, and for T6 condition it

decreases successively with increasing Sm content. In both conditions, plasticity of the

M g - S m alloys at 250°C is high enough not to be critical for their application as structural

materials. The different character of the elongation curves for 250°C as compared with

those for room temperature is connected with different behaviour of magnesium alloys

during plastic deformation at room and elevated temperatures.
