Abstract
A brake rotor in which deformation against thermal stress is reduced, thereby preventing a surface layer from being cracked or peeled upon operation of the brake rotor at a high temperature. A titanium alloy is heat-treated at a .beta. phase transformation temperature and is quenched, so that grains of the alloy are equiaxed up to sizes ranging from 300 .mu.m to 4 mm, whereby deformation against thermal stress is significantly improved.
