The Rupture behavior of these joints has been investigated at stresses in the range 180–220MPa. In the present paper an attempt has been made to present the results on the creep failure mechanisms of creep–ruptured laser welded 316L(N)SS joints. It has been observed that creep fracture ...
- 《Materials Science & Engineering A》 被引量: 47发表: 2011年 Transition in Failure Mechanism Under Cyclic Creep in 316LN Austenitic Stainless Steel Cyclic creep behavior of a type 316LN austenitic stainless steel was investigated in the temperature range from 823 K to 923 K (550 °C to ...
Starting from an elastoplastic model for the description of short term behavior, the time-dependent deformation is described in terms of evolution of microstructure, leading to progressive degradation of elastic modulus and failure strength of material. The proposed model is applied to predict material ...

However, the failure of alloys at 850 or 900?°C presented necking to a point due to the microstructure degradation. Further investigations showed the softening of materials and the loss of mechanical performance could...
The origin of the Monkman-Grant relationships for these materials is discussed in terms of stress exponents, specific interfacial areas, and ratio of secondary strain to failure strain. 展开 关键词: materials science creep fracture properties aluminium aluminium oxides composite materials particulates ...

However, SAF 2205 was significantly more resistant than 316 as far as the number of cycles to failure and the sulphidizing attack at the external surface were concerned. In both materials, the creep-fatigue crack propagation was directly controlled by the environmental attack of the SO 2 -...
