Abstract AR
مسبوكة Al و Al-Ni-Cr (المحتویة على نسب مختلفة من Ni-Cr بالمقدار 0.25, 0.5, 0.99, 1.98) المحضرة بإذابة أسلاك من الألمنیوم مع مسحوق النیكل و قطع صغیرة جدا من الكروم في فرن كهربائي بدرجة حرارة مقداره 800 °C تحت فراغ من الاركون.
بعد المعاملة الحراریة للنماذج المحضرة بدرجة 560 °C لفترة 1300 hr, یبین حیود الأشعة السینیة ظهور و نمو ثلاثة أطوار ثنائیة : Al3Ni (معيني, a = 7.352, b = 7.352, c = 4.802), Cr9Al17 (موشوري سداسي, a = 12.910, c = 15.677) و Ni2Cr3 (رباعي الزوايا a = 8.85, c = 4.58) إضافة إلى اطوار غیر معروفة.
الحجم الحبیبي یقل بزیادة محتوى Ni-Cr في السبیكة باستثناء النسبة 1.98 at%.
النتائج تشیر إلى زیادة الصلادة الدقیقة ثلاثة اضعاف بزیادة الكثافة بمقدار 0.1 g/cm3.
Abstract EN
Ingots of Al and Al-Ni-Cr (contains 0.25, 0.5, 0.99, 1.98 at.
% Ni-Cr) alloys were prepared by melting together wire aluminium, powder nickel and very small pieces of chromium in an electric furnace at 800 oC under an argon atmosphere.
XRD analysis after exposed the alloys to annealing at 560 oC for 1300 hr showed the emergence and growth of three binary phases: Al3Ni (Orthorhombic, a = 6.598Ǻ, b = 7.352 Ǻ, c = 4.802 Ǻ), Cr9Al17(Rhombohedral, a = 12.910, c = 15.677 Ǻ), and Ni2Cr3(Tetragonal, a = 8.82 Ǻ, c = 4.58 Ǻ) in addition to unknown phases.
The crystallite size decrease with increasing Ni-Cr contents exception the ratio 1.98 at.
%.
The results refer to rising of microhardness three times when raised the alloy density 0.1 g / cm3.
