A pseudobinary phase diagram is an equilibrium diagram calculated for a ternary or higherorder system, in which the phase boundaries resulting from the variation of two of the element contents are calculated, while the amounts of all the other elements are kept constant This is similar in many respects to the FeFe3C diagram calculated inCementiteor iron carbide is very hard, brittle intermetallic compound of iron & carbon, as Fe3C, contains 667 % C It is the hardest structure that appears on the diagram, exact melting point unknown Its crystal structure is orthorhombic It is has low tensile strength (approx 5,000 psi), but high compressive strengthThe fraction of each phase present in a two phase region of a binary phase diagram is determined using a a tie line b the lever rule c Fick's 1st law d a diffusion coefficient 12) Term used to describe failure under cyclic stresses below the yield stress is a) creep b) case hardening c) fatigue d) ductile failure 7
Actually, the phase diagram extends on the abscissa axis at left from pure iron free of carbon to a content of total carbon reaching 670 wt% C that corresponds to the theoretical composition of iron carbide or cementite (Fe 3C), while temperatures range from 0°C to 1600°C, the temperature at which the system is fully liquid The binary Hence, the normal equilibrium diagram which is generally used is the metastable FeFe3C diagram because it is relevant to the behaviour of most steels in practice The details of the stable and metastable phase diagrams of the FeC system, especially on the Ferich side, are known much better than any other binary systems with similar complexityในระบบที่ประกอบด้วยโลหะ 2 ชนิด (Binary phase diagram) ที่มีการ 12 Figure 92 The coppernickel phase diagram 3 ปริมาณหรือสัดส่วนของ Phase ที่ปรากฏอยู่ (Phase Amounts) 2
