Google Scholar Web2 jul. 2024 · It is stable above 727°C in plain carbon steels but can be obtained at room temperature, say by adding elements like Ni or Mn in steels and the micro-structure is illustrated in Fig. 1.21 (a) with one unit cell outlined of a grain of polyhedral structure. WebThe microstructure of annealed hypereutectoid steel will consist of coarse lamellar pearlite areas surrounded by a network of a proeutectoid cementite. Because this excess cementite network is brittle and tends to be plane of weakness, full annealing should never be a final heat treatment process for hypereutectoid steels. guyana city council number
