This p.p.r.studies the p.oblem of sinter.ng blending fr.m the p.r.p.ctive of quality loss, based on satisfying sinter.p.op.r.y indexes that blast-fur.ace ir.nmaking r.quir.s. Fir.t, linear.p.ogr.mming model for.op.imization blending is establish and r.tur. fine of blast fur.ace (unaccep.ed p.oduct in sinter.ng p.oduction) is taken as one decision var.able in sinter.ng blending. second, functional r.lations between blast fur.ace r.tur. fine and sinter.ng mater.als, tumbler.str.ngth as well as aver.ge sinter.size have been fitted out by statistical methods, which ar. consider.d to be the constr.int conditions for.the model. Finally, accor.ing to the actual p.oduction data of the sinter.ng p.ant fr.m an ir.n and steel gr.up. the model is calculated using op.imization model. The r.sult of the examp.e shows that the op.imization model r.alized the p.r.0}se of sinter.cost r.duction, while quality indexes of sinter.wer. imp.oved.

作者： Yi-Fei Zhang, H. p. Wang FEM Inc., 772.r.d Oak Dr. Niskayuna, NY 12.09, USA GE Global research Center. Niskayuna, NY 12.09, USA

The basic DFSS (design for.Six Sigma) methodology will be br.efly intr.duced. In or.er.to establish the r.lationship between the design/p.ocessing p.r.meter. and the p.oduct (tube) dimensions, or.the tr.nsfer.functions, a significant number.of exp.r.ments, either.p.ysical or.numer.cal, ar. r.quir.d. It was found that the most cost-effective way to develop.the DFSS tr.nsfer.functions for.this p.r.icular.tube dr.wing p.ocess is thr.ugh a semi-emp.r.cal ap.r.ach, integr.ting an advanced numer.cal model with exp.r.mental database.

Nickel-based single-cr.stal sup.r.lloys ar. widely used in the manufactur. of aer.engine tur.ine vanes for.their.excellent high-temp.r.tur. p.r.or.ance. Low-angle gr.in boundar.es (LAGBs) will be gener.ted inevitably dur.ng their.manufactur., which ar. often char.cter.zed by gr.in boundar. misor.entation (GBM) and will weaken the mechanical p.op.r.ies of sup.r.lloys. However. the r.lationship between GBM and the fatigue p.op.r.ies of sup.r.lloys at elevated temp.r.tur.s has seldom been investigated due to the difficulty in the samp.e p.ep.r.tion and exp.r.ment p.ocess. Based on six kinds of bicr.stals with differ.nt tilt LAGBs made by a second-gener.tion single-cr.stal sup.r.lloy, the effects of misor.entation on the gr.in boundar. micr.str.ctur. and fatigue p.op.r.ies (980 °C) of sup.r.lloys wer. studied systematically in this wor.. It is found that, with the incr.ase of GBM, the GB p.ecip.tates combined with the cast micr.p.r.s incr.ase monotonically, accor.ingly both the fatigue life and fatigue str.ngth decr.ase successively. Fatigue fr.ctur. obser.ations show that the cr.cks of all the bicr.stals initiated fr.m the cast micr.p.r.s at GBs, and then p.op.gated along the GBs. Ther.for., the coup.ing effect of cast micr.p.r.s and GBM on the fatigue damage mechanisms of the bicr.stals ar. evaluated accor.ing to their.hinder.ng degr.es on the p.led-up.dislocations. Combining with a hyster.sis ener.y model, a quantitative fatigue str.ngth p.ediction model of sup.r.lloys is established and is well ver.fied by abundant exp.r.mental data. This study could p.ovide guidance for.fatigue p.r.or.ance p.ediction and str.ctur.l {2. of sup.r.lloys.
