Introduction

Literature data up to 1990 are given in the review done by [1990Gok]. This diagram presents eight solid phases, namely R-Mn₆Si, ν-Mn₉Si₂, αMn₃Si, βMn₃Si, Mn₅Si₂, Mn₅Si₃, MnSi and MnSi_1.75, the phases R, ν and Mn₅Si₃ being non stoichiometric. It is accepted by [2006Gup1, 2006Gup2] for the description of the Co-Mn-Si and Mn-Ni-Si systems. Between the phases R and ν, [1965Gla, 2004Jou] reported the existence of a μ phase, but this is not taken into consideration in the following diagrams. As a consequence, we shall consider this μ phase as metastable. Subsequently, the Mn-Si system was studied by several techniques and for different temperature and concent...
