Improvement of the fatigue crack growth resistance in AISI 4140 steel under single- and multi-austempering heat treatments
AISI 4140 steel under annealing conditions was subjected to single- and multi-austempering heat treatments. The mechanical performance of the compact tension (CT) specimens was evaluated via axial tensile tests and fatigue crack growth (FCG) tests. The single-austempered steel showed a significant i...
