The invention relates to a functionally graded material shape (1) where a first material (M1) is fused with a second material (M2) through sintering and a method of production of said functionally graded material shape (1). Said first material (M1) has a first coefficient of thermal expansion (α1) and said second material (M2) has a second coefficient of thermal expansion (α2), differing from the first coefficient of thermal expansion (α1). The invention is characterized in that the shape (1) further comprises a third material (M3) adapted to, together with M1 and M2, create an intermediate composite material phase intermixed between the first and the second materials (M1, M2). Said third material (M3) has a coefficient of thermal expansion (α3) intermediate between the first coefficient of thermal expansion (α1) of the first material (M1) and the second coefficient of thermal expansion (α2) of the second material (M2).
A functionally graded material shape, where a first material, which is a metal or metal alloy, is fused with a second material, which is a ceramic material, a metal or a metal alloy, through sintering, said first material has a first coefficient of thermal expansion (α1) and said second material has a second coefficient of thermal expansion (α2), differing from the first coefficient of thermal expansion, characterized in that the shape further comprises a third material adapted to create an intermediate composite material phase intermixed between the first and the second materials, said third material is a metal or a ceramic additive and has a coefficient of thermal expanion (α3) intermediate between the first coefficient of thermal expansion (α1) of the first material and the second coefficient of thermal expansion (α2) of the second material.
