철강(鐵鋼) 및 알루미늄재료(材料)의 기계적(機械的) 성능(性能)에 미치는 TMT(thermomechanical treatment)의 영향

The Effect of TMT on Mechanical Properties of Steel & Aluminum Alloy

A study has been performed on the effect of TMT(thermomechanical treatment) on the mechanical properties of steel and aluminum alloys. Improvement of the mechanical properties on steel by HTMT is due to refinement of prior austenite grain size, martensite lath size and the distribution of fine carbide precipitates and on aluminum alloy by ITMT is due to grain size refinement, homogeneous distribution of small second phase particles and retardation of the recrystallization.
