Methods of production of Metallic Glasses
Metallic glasses are manufactured by the following methods. They are,
1. Twin roller technique
2. Melt extraction technique
3. Melt spinning technique
Melt spinning technique
Principle
Quenching is a technique used to form metallic glasses. Quenching
means Rapid Cooling.
Due to rapid cooling, atoms are arranged irregularly and from metallic
glasses.
Melt spinning Technique
A melt spinner consists of a copper roller over which a
refractory tube with fine nozzle is placed.
The metal alloy is melted by induction heating under inert gas
atmosphere (helium or argon). The properly super heated
molten alloy is ejected through the fine nozzle at the bottom of
the refractory tube.
The molten alloy falls on the copper roller which is rotated at
high speed. Thus, the alloy is suddenly cooled to form metallic
glass. In this method a continuous ribbon of metallic glass can
be obtained. By increasing the disc speed and making ejection
pressure constant, increases the width of the ribbon and
decreases the thickness of the ribbon.
Glass transition temperature
It is an important parameter for the preparation of metallic glasses. It is defined as
a temperature at which the liquid like atomic structure is obtained into a solid.
The value of glass transition temperature for metallic alloys is about 200C to 300C

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

3. INTRODUCTION
SMART MATERIALS
Smart or intelligent materials are materials that
have to respond to stimuli and environmental changes
and to activate their functions according to these
changes.
The stimuli like temperature, pressure, electric flow,
magnetic flow, light, mechanical, etc can originate
internally or externally.
4. PROPERTIES OF SMART
MATERIALS
• Sensing materials and devices
• Actuation materials and devices
• Control devices and techniques
• Self-detection, self-diagnostic
• Self-corrective, self-controlled, self-healing
• Shock-absorbers, damage arrest
6. • Piezoelectric Materials: When subjected to an
electric charge or a variation in voltage, piezoelectric
material will undergo some mechanical change, and
vice versa. These events are called the direct and
converse effects.
The Direct Effect The Reverse Effect
7. • Electrostrictive Materials: This material has the
same properties as piezoelectric material, but the
mechanical change is proportional to the square of
the electric field. This characteristic will always
produce displacements in the same direction.
8. • Magnetostrictive Materials: When subjected to a
magnetic field, and vice versa (direct and converse
effects), this material will undergo an induced
mechanical strain. Consequently, it can be used as
sensors and/or actuators. (Example: Terfenol-D.)
9. • Rheological Materials: These are in liquid phase
which can change state instantly through the
application of an electric or magnetic charge. These
fluids may find applications in brakes, shock
absorbers and dampers for vehicle seats.

10. • Thermoresponsive Materials: Thermoresponsive is
the ability of a material to change properties in
response to changes in temperature. They are useful
in thermostats and in parts of automotive and air
vehicles.
11. • Electrochromic materials: Electrochromic is the
ability of a material to change its optical properties
(e.g. Color) when a voltage is applied across it. They
are used in LCDs and cathodes in lithium batteries.
12. • Fullerences: These are spherically caged molecules
with carbon atoms at the corner of a polyhedral
structure consisting of pentagons and hexagons.
These are usually used in polymeric matrices for use
in smart systems. They are used in electronic and
microelectronic devices, super-conductors, optical
devices, etc.
13. • Biomimetic Materials: The materials and structures
involved in natural systems have the capability to
sense their environment, process the data and
respond instantly. For example: to allow leaf surfaces
to follow the direction of sunlight and essentially a
real-time change in the load path through the
structure to avoid overload of a damaged region.
The field of biomimetic materials explores the
possibility of engineering materials and structures.
14. • Smart gels: These are gels that can shrink or swell
by several orders of magnitude. Some of these can
also be programmed to absorb or release fluids in
response to a chemical or physical stimulus. These
gels are used in areas such as food, drug delivery,
organ replacement and chemical processing.
15. SHAPE MEMORY ALLOYS
In 1930s, Arne Olander was first observed the shape
memory effect while working with an alloy of gold and
cadmium.
This Au-Cd alloy was plastically deformed when cold but
returns to its original configuration when heated.
The shape memory properties of nickel-titanium alloys
were discovered in the early 1960s. Although pure
nickel-titanium has very low ductility in the
martensitic phase, the properties can be modified by
the addition of a small amount of a third element.
These groups of alloys are known as Nitinol™
(Nickel-Titanium-Naval-Ordnance-Laboratories).
16. How SMA Works?
• SMA occurs due to the change in the crystalline
structure of materials.
• Two phases are:
Martensite:
• Low temperature phase
• Relatively weak
Austenite:
• High temperature phase
• Relatively strong
20. APPLICATION
S
• Aircrafts
• Orthopedic surgery
• Dental braces
• Robotics
• Reducing vibration
of helicopter blades
• Smart fabrics
• Sporting goods
• Smart glass
21. MERITS
• Bio-compatibility
• Simplicity
• Compactness
• Safety mechanism
• Good mechanical
properties
DEMERITS
• More expensive
• Low energy efficiency
• Complex control
• Limited bandwidth
22. Conclusion
• Today, the most promising technologies for lifetime
efficiency and improved reliability include the use of
smart materials and structures. Understanding and
controlling the composition and microstructure of any
new materials are the ultimate objectives of research
in this field, and is crucial to the production of good
smart materials.
• New and advanced materials will definitively enhance
our quality of our life.
