“…Mujiyono et al (2018) manufactured a BNCT collimator from nickel using centrifugal casting. Casting is a manufacturing method to produce a metal material, and centrifugal casting is a casting method that uses centrifugal force from the rotating mould (Iqbal et al 2014;Ebhota et al 2016).…”

In this study, Rockwell and Brinell hardness testing was used to examine material hardness. These methods were chosen because they are easy to carry out, relatively inexpensive, and almost all sizes and shapes can be tested, in which nickel hardness before and after centrifugal casting are identified and compared. These tests enable the determination of the hardness numbers of nickel collimators using for boron neutron capture therapy. The samples were five nickel plates with a dimension of 4.5 × 4.5 cm and five collimators. The collimators were cylindrical and made using centrifugal casting.

“…Centrifugal casting process increases cooling rate and consequently, produces small dendritic cells, small inter-dendrite arm spacing and small lakes of Si. Alloys of Al-Si by CCT are morphologically transformed from acicular to ibrous [52]. Micrographs of A390-5%Mg alloy as-cast fabricated by gravity casting and CCT are shown in Figure 16.…”

“…Some studies have reported that mould rotational speed range of 1200-1500 RPM as the optimum [53] and other relevant processing parameters are pre-heating and pouring temperatures [52]. The efect of CCT on casting can be classiied into three: centrifugal pressure, inherent vibration of the process and luid dynamics.…”

Mechanical, physical and chemical properties of a part depend on the size, morphology and dispersion of the constituents of the microstructure of the part's material. Therefore, this chapter discusses the diferent processes of altering the microstructure of Al-Si-based alloys to desired functional properties. These processes, commonly called modiication methods, were broadly categorised into three: chemical, thermal and mechanical methods. Chemical method, which involves the addition of some elements, in trace levels, to alloys to be modiied, is the best modiication option. The elements for modifying are called modiiers. The three commonly used modiiers (sodium, Na, strontium, Sr and antimony, Sb) are discussed. The chapter, however, notes that for optimal alloy's mechanical atributes, thermal treatment is usually combined with both chemical and mechanical modiication processes. The thermal method involves rapid cooling of alloy for modiication, while the mechanical method depends on force to break up large α-Al dendrites and plate-like Si phases.

“…The metal matrix and reinforcement density difference cause segregation in which the particles with higher density move to the outer region and lower density particles migrate to the inner surface. The grading defines the functionality and can be controlled and improved by processing variables such as centrifugal rotation speed, molten metal alloying temperature, particle size and volume, mould temperature, and cast geometry [51].…”

This chapter discusses the concepts, casting techniques and applications of functionally graded materials metal matrix composites (FGMMCs). Considerations were given to bulk functionally graded aluminium matrix composites (FGAACs) production processes. Liquid-metal forging processes of FGAACs fabrication, such as infiltration process, squeeze casting, friction casting or compocasting, stir, and centrifugal casting were discussed. The chapter provides basic concepts of the processes and overview of their processing parameters, such as mould rotational speed; reinforcement particles size and volume; degassing method; melting and pouring temperatures; pressure; and stirrer. The study notes that functionally graded materials (FGMs) are commonly used in automotive, aircraft, aviation, chemical, medical, engineering, renewable energy, nuclear energy, and optics electronics industries.
