...–1932) and end-quench hardenability testing by Walter E. Jominy (1893–1976) An important result of the early metallographers was the naming of the phases and multiphase microstructures found in steels ( Ref 2.14 ). Howe, 1888, suggested the names ferrite, cementite , and pearlite for the phases...
