    Summary:The selective laser melting(SLM) is a kind of additive manufacturing processes, which melts the thin powder layer selectively and forms 3D object by compiling many layers. To obtain the proper laser melting conditions for SLM process, the prediction of thermal field around the scanning laser spot is necessary. In this paper, a finite element method of transient heat conduction analysis is proposed to predict the thermal field. It is based on the energy conservation equation for enthalpy of bulk metal, powder metal and once-melt-and-solidified powder metal. The method includes the phenomena of melting and solidification of powder metal. The numerical simulation using this method is applied for Ni-based refractory alloy, Inconel-718, and the results of the simulation is presented with temperature contours and dimensions of melt pool.Ⅲ.論文集
  • OS1735 Brazing of C/C composites and Ni-based alloy with stress relieving layer, IKESHOJI Toshi-Taka, SUZUMURA Akio, YAMAZAKI Takahisa, M&M材料力学カンファレンス, 2014, "OS1735, 1"-"OS1735-2",   2014 07 19 , http://ci.nii.ac.jp/naid/110009939704
    Summary:C/C composites plate was brazed to Ni-based alloy, Inconel-600 plate using Fe-Cr-Ni-(Si,P) brazing filler metal with various thickness of Nb foil inserted. Niobium foil was solved into the brazing filler layer and precipitated along the C/C composites' surface. Although, Nb layer remained in the brazed interface was thinner than the original Nb foil thickness, it acted as the stress relief layer. The shear strength of brazed joint varied with the remained Nb layer's thickness. The shear strength increased for the brazed joint with 100μm of Nb layer, but once dropped for the joint with 200μm. The FEM analysis revealed that the shear strength of brazed joint monotonously increase with Nb layer's thickness. The microstructure in the brazing filler layer was considered to contribute to the tendency of the shear strength with Nb layer thickness.
