AbstractThe coarse microstructure of the as-cast Fe-0.8 B-1.3 C-1.6 Cr (wt%) alloy was refined by a thermomechanical processing consisting of rolling at 1050 °C (ε = −2.8) and then rolling from 950 to 670 °C (ε = −1). The final microstructure consists of very fine cementite particles and small, and some large, borocarbide particles in a fine-grained ferritic matrix. A stress exponent of about 2.5 at low strain rates and a maximum elongation to failure of 98% was observed at temperatures ranging from 660 to 720 °C.
