“…Figure shows four examples of typical optical micrographs of the surfaces of hot rolled and hot forged specimens. In Figure a a general aspect is shown of the surface of a hot rolled specimen, revealing a series of equiaxed grains with multiple twins, representing a typical aspect of austenite in Fe–Mn–Si shape memory alloys . The detailed view allows observing the presence, besides equiaxed grains, of many banded zones which suggest the occurrence of a martensite‐type transition, Figure b.…”

“…These processes were applied at 1373 K, in order to reduce thickness to 1 × 10 –3 m. Hot working was performed repetitively, both by rolling (7 passes) and forging (7 blows). Hot rolling was performed with an experimental setup, comprising a tubular electric furnace and flat cylinders roller, while hot forging was accomplished by means of an electric furnace close to a pneumatic free‐forging hammer . After each rolling pass or forging blow the specimens were reheated to 1373 K. After reaching 1 × 10 –3 m‐thickness, the specimens were finally cooled in air.…”

“…After pressing (500 MPa) and sintering (under argon atmosphere at 1423 K for 2 u 3.6 ks), in order to further increase specimens compactness, six consecutive hot rolling passes were performed at 1373 K, without allowing the billets to cool down to room temperature (RT), until reaching a thickness of 1 mm [17]. Hot rolling was performed with an experimental setup, comprising a tubular electric furnace and flat cylinders roller, which seized the billets when being pushed out the furnace, by a long flat-head rod [18]. With this procedure specimens' porosity degree decreased from 16.85 % at 0_MA to 2.51% at 50_MA.…”

“…The ball bearings industry benefits f rom the advances in material science. Many composite materials and new metallic alloys are being tested and used in the ball bearings manufacturing processes and shape memory alloys [2] can be used in various devices and machines that rely on ball bearings [3]. The idea of using SMA as control devices for optimum preload of angular contact ball bearings (ACBB) is new, being advanced by the authors in [4][5][6].…”
