Hazard Evaluation of Carbon Steel Water Tube Boiler under Explosion Behavior Haoyang Du1,2,a, Yong Zhao 3,b, Zhen’an Ren 1,c 1 College of Materials Science and Engineering, Jilin University, Changchun, 130022 China 2 Electric Power Research Institute of Jilin Electric Power Co.
The main material for the boiler is carbon steel.
Two largest pieces among the widely spreaded broken pieces are chosen, which are assumed 2% of the total energy. 3.2 Energy consumed in cast pieces The cast energy of broken pieces is calculated as formula： (1) －energy consumed in broken piece -Weight of broken piece， (2) density of material,7.9×,-area,shell thickness, mm Here the area of piece A is 10m2, B is 2.56 m2 ,the measured thickness is 6.0mm..

Over the past decades of years HA and related calcium phosphates have been widely used as implant materials due to their close similarity of composition and superior biocompatibility with natural bone.
It is well known that the mechanical strength of a material generally decreases as its porosity increases.
The conflicting Title of Publication (to be inserted by the publisher) interests between biological and mechanical requirements thus pose a challenge in developing porous materials for load-bearing bone tissue engineering.
