آلیاژهای اینکونل، خانواده ای از سوپرآلیاژهای پایه نیکل هستند که محدوده وسیعی از ترکیبها و خواص را در برمی گیرند. اینکونل 718 جزئی از این سوپر آلیاژ ها می باشد که به دلیل خواص مکانیکی مناسب مانند استحکام خزشی و مقاومت در برابر خوردگی در دمای بالا، در صنایع هوافضا مورد استفاده قرار می گیرد. علیرغم این مزیت ها، اینکونل 718 به سختی ماشینکاری می شود. در این مقاله فرآیند ماشینکاری متعامد اینکونل 718 ...

ABSTRACT Inconel 718 is a difficult-to-cut nickel-based superalloy commonly used in aerospace industry. This paper presents an experimental study of the tool wear propagation and cutting force variations in the end milling of Inconel 718 with coated carbide inserts. The experimental results showed that significant flank wear was the predominant failure mode affecting the tool life. The tool fla...

In this paper we discuss the designs of 2-channel orthogonal near symmetric wavelets on the one hand, and the symmetric near orthogonal wavelets on the other. In both types of wavelets we use the Gröbner bases design approach and present examples of both cases. ةــصلاخلا ةهج نم نيتانـق تاذ ةلـثامتملا هبش ةدماعتملا ةريّـغصلا تاجوملا ميمصت ثحبلا اذه يف شـقانـنُ فوس تاجوملا يعون لاك يف لمعتسن فوسو ....

Laser direct metal deposition (LDMD) has developed from a prototyping to a single metal manufacturing tool. Its potential for creating multimaterial and functionally graded structures is now beginning to be explored. This work is a first part of a study in which a single layer of Inconel 718 is deposited on Ti-6Al-4V substrate. Single layer tracks were built at a range of powder mass flow rates...

Workload characterization is used for modeling and evaluating computing systems at different levels of detail. We present workload characterization for a class of Computational Fluid Dynamics (CFD) applications that solve Partial Differential Equations (PDEs). This workload characterization focuses on three high performance computing platforms: SGI Origin2000, IBM SP-2, and a cluster of Intel P...
