Description
図2は、実施例1に対する比較例として、LMDによる積層造形を行う際の複合材料Aの断面における形状、および積層物の位置関係を示す。なお、説明上の方向として、X方向、Y方向、Z方向を示す。X方向、Y方向は、水平面を構成する直交する2つの方向である。Z方向は鉛直方向である。
図4、図5は、実施例1に対する比較例として、LMDによる積層造形を行う際の複合材料Aの断面における形状、および積層物の位置関係を示す。なお、説明上の方向として、X方向、Y方向、Z方向を示す。X方向、Y方向は、水平面を構成する直交する2つの方向である。Z方向は鉛直方向である。
実施例1の複合材料は、Fe合金相、Cu相と基材で構成された複合材料であり、Cu相2がFe合金相1に包囲されており、なおかつCu相2が基材3とFe合金相1の境界面に対して垂直な方向へ大となる異方性形状を形成する複合材料である。
図7は、実施例2の複合材料における断面図で、図7はX方向とZ方向を含む平面で切断した状態を示す。図7では、造形対象である複合材料(造形物とも呼ぶ)Aを構成するFe合金相1、Cu相2を備えている。Cu相2はFe合金相1に包囲されており、なおかつZ方向に大である形状を備えている。
図8は、実施例3の複合材料における断面図で、X方向とZ方向を含む平面で切断した状態を示す。図8では、造形対象である複合材料Aを構成するFe合金相1、Cu相2、基材3、表面を構成する表面相10を備えている。Cu相2はFe合金相1に包囲されており、なおかつZ方向に大である形状を備えている。
実施例1と違い、Fe合金相1およびCu相2は基材3との接触面と反対の位置に表面相10と接触している。表面相10はFe合金相1の表面に造形しても、Fe合金相1に接合してもかまわない。
