Analysis of Factors Determining Aspects of Deformation and Hardening of Bronze BrNHK2.5–0.7–0.6

The study investigates the optimization of heat treatment modes for bronze BrNHK2.5–0.7–0.6 to enhance its mechanical properties, crucial for applications in machinery and instrument manufacturing. It explores the influence of heat treatment temperatures and durations on the alloy's strength and hardness, highlighting the significance of aging at specific temperatures and times. The research also employs acoustic emission (AE) analysis to assess the effects of grain size and phase composition on the alloy's behavior under stress. The findings reveal that optimal heat treatment conditions significantly improve the alloy's properties, while inhomogeneous phase distribution can lead to reduced ductility. The use of AE as a non-destructive testing method is emphasized, providing valuable insights into the alloy's deformation and failure mechanisms.
