In order to evaluate the strength and ductility of a material whose size and shape are limited, it is quite valid to apply the bend tests by using miniaturized specimens. In this study bend tests and tensile tests were performed for doped molybdenum with an elongated grain structure. Then influence of specimen thickness and test method on the low-temperature strength and ductility was discussed. In this study the fracture strength and ductility particularly at low temperatures were represented by two parameters, critical stress and critical temperature respectively.<BR>Results are summarized as follows. First, influence of specimen thickness ranging 0.5-1.0mm on the critical stress and critical temperature was not recognized for doped molybdenum with an elongated grain structure. Secondly, relationship between yield strength (σyt) by tensile tests and that (σyb) by bend tests was σyt=σyb/1.74 for doped molybdenum with an elongated and very large grain structure.
