抄録

The effect of the prestrain and annealing temperature, and atomosphere on the mechanical properties and etch pits observed on (111) sur faces of molybdenum wires were investigated. The dislocation etch pits were revealed by etching with potassium ferricyanide-caustic soda solution after heat-treatment at 1200°C in hydrogen atomosphere, but not after vacuum treatment at 1200°C. A correspondence between the appearance and disappearance of etch pits and of the yield points was observed. The array of etch pits and subboundaries were observed after heat-treatment using a heating current equal to 90% of the fusion current.
