The effects of austempering time on mechanical properties of the novel GCr15Si1MoNbV bearing steel and on its rolling contact fatigue behaviors

Puntos clave

• Increased austempering time improves mechanical properties and reduces rolling contact fatigue.
• Key findings include enhanced toughness and fatigue life after specific timeframes of austempering.
• Assessment of mechanical properties involved stress tests and fatigue evaluations on samples of GCr15Si1MoNbV steel.
• Results indicate that tailoring austempering time can potentially optimize performance in bearing applications.
