On the Brittleness of Heat-affected Zone (Report 5)
JOURNAL OF THE JAPAN WELDING SOCIETY, 1955 It is recognized that the impact-resistance of sharp-notched specimen decreases suddenly at the so-called "transition temperature". Below this temperature the fracture shows more brittle than shear one and at low temperatures the shear fracture vanishes.

Microstructural investigation of the heat-affected zone of simulated welded joint of P91 steel
Metalurgija, 2013 In the process of testing real components exposed to elevated temperature, it is not possible to neglect cracks. The most significant cracks can be induced by welding, which is applied for joining of structural components.
