BCC metals (transition metals) have _____ yield strength temperature sensitivity.

BCC metals (transition metals) have _____ yield strength temperature sensitivity. Correct Answer Large

BCC metals show activation of slip planes on the higher temperature. So these show large yield strength temperature sensitivity. Their yield strength decreases on low temperatures.
