A well-written lab report abstract must highlight four essential aspects of the report, which is its purpose, the method, results, and conclusion. ABSTRACT. Annealing, normalizing and age-hardening heat-treatments at 850oC were used for the experimental work. In particular, various heat treatments for a given steel alloy allow the development of a number of alternative microstructures, which in turn, affect the mechanical properties of the steel. Complete and partial annealing heat treatments are the only ones used for the non-heat treatable alloys. Heat treatment practices used by steel foundries have been carefully studied as part of comprehensive heat treatment procedure qualification development trials. The heat treatment is done to improve the machinability.
