Influence of Joining Strength of Si3N4/S45C on Residual Stress

Abstract

Abstract: According to Si₃N₄/S45C joining sample with soft metal interlayer in the thermalload, the effect of residual stress on bending strength was studied.

Some results obtained are as follows. (1) The tension stress in the edge of Si₃N₄ section is mainly reason to affect the bonding strength. (2) There is a linear
relationship (σ₀=-1.63σ+658.1) between the bending strength and the residual stress. (3) The heat cycle results in machining hardening of join samples,
so that the residual stress increases and at the same time the cracks formed make the strength decreased.

Key words: ceramics, metal, joining, residual stress, bending strength, heat cycle
