t.e t.ermoelect.ic energy conversion t.chnique by employing t.e Disk-Magnet.Elect.omagnet.c Induct.on (DM-EMI) is examined in det.il, and possible applicat.ons t. heat.engines as one of t.e energy-harvest.ng t.chnologies are discussed. t.e idea is induced by t.e analysis of t.ermomechanical dynamics (t.D) for a nonequilibrium irreversible t.ermodynamic syst.m of heat.engines, such as a drinking bird and a low t.mperat.re St.rling engine, result.ng in t.ermoelect.ic energy generat.on different.from convent.onal heat.engines. t.e current.t.ermoelect.ic energy conversion wit. DM-EMI can be applied t. wide ranges of machines and t.mperat.re differences. t.e mechanism of DM-EMI energy convert.r is cat.gorized as t.e axial flux generat.r (AFG), which is t.e reason why t.e t.chnology is applicable t. sensit.ve t.ermoelect.ic conversions. on t.e ot.er hand, almost.all t.e convent.onal t.rbines use t.e radius flux generat.r t. ext.act.huge elect.ic power, which uses t.e radial flux generat.r (RFG). t.e axial flux generat.r is helpful for a low mechanoelect.ic energy conversion and act.vat.ons of wast. heat.from macroscopic energy generat.rs such as wind, geot.ermal, t.ermal, nuclear power plant. and heat.dissipat.on lines. t.e t.chnique of DM-EMI will cont.ibut. t. solving environment.l problems t. maint.in clean and sust.inable energy as one of t.e energy harvest.ng t.chnologies.

采用热力学计算和实验技术研究铝角的Al-Ca-Fe体系相图,包括液相面投影图和凝固反应。结果表明,与铝固溶体(Al)平衡的不是Al_(3)Fe相,而是一种组成符合化学式Al_(10)CaFe_(2)的三元化合物。通过包晶转变L+Al_(3)Fe→(Al)+Al_(10)CaFe_(2)(638℃,3.3%Ca和0.5%Fe,摩尔分数)发生从二元化合物到三元化合物的转变。与针状Al_(3)Fe相夹杂物不同,三元化合物的初晶和共晶具有致密的形貌。使用第一性原理计算和X射线衍射分析确定三元化合物Al_(10)CaFe_(2)的晶格结构。此外,近共晶合金Al-6%Ca-1%Fe(质量分数)在500~600℃退火后具有细晶组织,过量相的总体积分数约为25%。因此,Al-Ca-Fe体系可用于制造新的铝基复合合金。
