In this investigation, with increasing oxidation time or temperature, the observed mass gain abided by the parabolic law. TiCN-HfC-WC cermet contained different layers, with each one having a unique composition. Thermal fracture occurred in the sub-oxidation layer, and the flexural strength gradually decreased from 1270.6 MPa to 149.9 MPa. Ther-mal stress equations for calculating the radial, circumferential, and axial stresses were es-tablished. The thermal stress differences between neighboring layers determined the ther-mal fracture; when they were zero, the physical parameters of the layers were related, which could be used to guide cermet material design.

Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.
