摘要： An impeller for a centrifugal compressor is characterized in that a shroud side of a front edge 7a of a splitter blade 7 is disposed so as to be displaced toward a negative-pressure surface Sb of a full blade 5F from a position equidistant from the full blades 5R and 5F in a circumferential direction such that a blade-end leakage vortex generated during a high flow rate which occurs from a blade-end clearance between the tip of the full blade 5F and a shroud toward the portion of the front edge 7a of the splitter blade 7 gets over the front edge 7a of the splitter blade 7.

摘要： A steel sheet contains, in terms of percent by mass, C: 0.01 to 0.2%, Si: 2.0% or less, and Mn: 3.0% or less and has a martensite phase as dominant phase and ferrite with a grain size of 20 μm or less as a second phase. The ferrite is contained in area ratio of 1% to 30% and the amount of solute carbon being 0.01 percent by mass of more. The steel sheet can provide a hot-rolled steel sheet suitable for automobile steel sheet, i.e., has excellent press workability and excellent strain aging property whereby the tensile strength significantly increases by heat treatment at about the same temperature as typical baking process after the press-working. Moreover, hardening of the ferrite phase improves the fatigue strength after the strain aging.
