Abstract

Abstract:

Oxidation reaction happened when Al₂O₃-TiC p composite heated at high temperature. The reaction producer moved to the crack area which induced crack healing. The heating temperature, time, and indentation affected the crack healing greatly. The kinetic analysis of crack healing of Al₂O₃-TiC p composite shows that: the strength recovery can be expressed by the following formula:σ_f/σ_f0=[1-2Δ(P·k^1/2_)/B₀·t^1/2]^-1/4, and the velocity
of crack healing can be showed as: - Cv/t=(C²_v0·ΔP)/(B₀C_v)·1/2·(k/t)^1/2. Reaction velocity constant, reaction time, the rate of volume increases due to reaction, and original crack size are four key factors of crack healing. The analysis of strength before and after crack healing proves the correctness of the crack-healing model.

Key words: crack healing, strength, velocity of healing, oxidiation reaction
