Introduction The need for joints between dissimilar materials often arises in automotive industries, because sound joints between dissimilar materials enable multi material design methodologies and low cost fabrication process to be employed.
From the point of view of material supply, aluminum alloy and steel are the most important construction materials for automotive structures; therefore, the availability of a sound joining technique between aluminum alloy and steel is indispensable.

Introduction Amorphous and nanocrystalline metallic alloys present a new category of materials with interesting mechanical, electric and magnetic characteristics [1-3].
However the applications of metallic glasses and nanocrystalline materials are still restricted due to high purity and a high price of the precursors.

The objective of this paper is to create a periodic review policy based on the ABC classification in order to control the raw materials more efficiently.
Two common inventory management policies are Just-In-Time (JIT) method, where companies plan to receive materials as they are needed rather than maintaining high inventory levels and Materials Requirement Planning (MRP), which schedules material deliveries based on sales forecasts.
Bill of materials, standard cost of materials, customer demand, route sheet, supplier information and order statistics data were collected.
The raw materials kept on the premises of the industry that is available for the production purpose is called stock.
Fig. 6 Release Order Quantity Model for Class C The following Table 3 shows the proposed model for one of the raw materials which is used for the production that will indicate how many to order and when to order.

Based on the theory of the plastic forming, the fillet size in the material mouth has a great influence on the material flow quality and the force on the die.
Material liquidity is greatly increased after the modification.
