Abstract : The tensile properties and tensile fracture behaviour of BIS 812 EMA and Q1N naval constructional steel weldments have been studied over a wide range of test temperatures utilizing plain and notched tensile specimens. Under certain conditions "star" fracture is the preferred fracture mode, rather than the usually observed cup-and-cone type fracture. The propensity for "star" fracture increases with decreasing temperature and the transition temperature for cup and cone to "star" fracture is reduced by notching. This paper describes the fracture surface features resulting from tensile tests and the conditions under which they occur in these materials. jg p.2
