Generative manufacturing processes and powder for this purpose

Generative manufacturing a component by multiple, sequential selective melting and / or sintering a powder (1) by means of a beam energy introduced by heat, so that the powder particles (1) in layers merge and / or sinter, characterized, in that - is preheated, the powder (1) or heated in addition to the beam energy, - the powder particles (1) of a first material (2) are formed, which is selected from the Group consisting of an Ni-based alloy, an Fe-base alloy, a Co-base alloy and an MCrAl alloy where M is Ni or Co, tungsten or a tungsten alloy and - the powder particles (1) are partially or fully covered by a second material (3) is surrounded, which is selected from the group consisting of boron, germanium and silicon, - the powder particles (1) are joined by weld, liquid or sinter in the solid phase by diffusion sintering, - wherein the second material (3) has a lower melting point than the first material (2) and having a degrading the melting point of the first material (2) property when welding, sintering or liquid in the solid phase by diffusion sintering with said first material (2) -.
