Ti.ani.m oxi.e Ti.;/epoxy and Ti.;wi.h detonati.n nano-di.mond（DND）/epoxy nanocomposi.es were prepared by usi.g ultrasoni.ati.n method. Ti.;and DND parti.les as rei.forcement speci.s and epoxy as matri. were used to produce nanocomposi.es. The addi.i.n of DND parti.les i.to Ti.;/epoxy composi.e i.proved the di.lectri. and mechani.al properti.s of nanocomposi.es i. si.ni.i.ant *** di.lectri. properti.s of Ti.;-DND/epoxy nanocomposi.e demonstrated i.crease i. permi.ti.i.y and conducti.i.y after addi.i.n of the DND parti.les. The maxi.um and mi.i.um reflecti.n losses of Ti.;-DND/epoxy nanocomposi.e for 0.6 and 0.2 wt% DND loadi.g were detected at -14.5 and -1.3 dB,respecti.ely. The flexural and tensi.e strength of Ti.;-DND/epoxy nanocomposi.es wi.h the addi.i.n of 0.4 wt% DNDs were enhanced to 220% and 223%, respecti.ely. Addi.i.nally, the energy to break and percent break strai. were 3.9 J and 3.86, respecti.ely for 0.4 wt% DND loadi.g i. Ti.;-DND/epoxy nanocomposi.e. Therefore, the present work fi.di.gs clai. that DND parti.les are well sui.able to enri.h the di.persi.n of Ti.;nanoparti.les i. epoxy matri., whi.h develops a strong load transfer i.terface between the nanoparti.les and epoxy matri. and consequently leads to superi.r properti.s.

Thi. paper presents comparati.e revi.w of experi.ental and thermodynami. assessment of ternary Ag-Sb-Zn system. i.othermal secti.n of the Ag-Sb-Zn system at 300 ~C has been calculated by CALPHAD method usi.g ther- modynami. parameters from li.erature. Mi.rostructural analysi. of a number of alloys was carri.d out by scanni.g electron mi.roscopy and opti.al mi.roscopy, whereas chemi.al composi.i.n of observed phases was analyzed usi.g energy- di.persi.e X-ray spectroscopy. Hardness of selected alloys from four verti.al secti.ns was determi.ed usi.g Bri.ell hardness test and addi.i.nally by mi.ro Vi.kers hardness test. Electri.al conducti.i.y of a number of alloys i. the ternary Ag-Sb-Zn system was experi.entally determi.ed. Good overall agreement between experi.ental and calculated values was obtai.ed.
